nstall hopper sections. When starting
to attach hopper sheets to sidewall it is
recommended that the first hopper
sheet seam be positioned halfway
between leg positions. Lap the hopper
sheets as shown. Use 5/16" x 1.1/4"
bin bolts (head to outside of tank) for
attaching hopper sheets to bottom
sidewall sheet. Use truss head bolts to
attach hopper sheet to hopper sheet.
Be sure to place the head of the truss
head bolt on the inside of the hopper.
Caulk all seams (double bead). Re­
member, the hopper collar must be
installed before the last hopper section
is in place. Clean any caulking, which
may have squeezed out during assem­
bly, off the inside of the hopper. After
the collar is in place, attach the hopper
braces and tighten all bolts.
